Though I've never built such a kernel, I'd imagine you could include iptables without the nat table, and thus not have a prerouting chain (since it's in the nat table). to the OP: maybe you just forgot the '-t nat' option to iptables? The PREROUTING chain is part of the nat table. When you don't specify a -t option, iptables uses 'filter' as the default table. good times, Vineet -- http://www.doorstop.net/ -- http://www.anti-dmca.org/
